BENZENE-HEATED STOVE.

Specifica-tion of Letters Patent.

Patented Feb. 1, 1921.

To aZZ whom it may concern:

Be it known that we, JOHAN Dimmi HOL- SCHER, tinker, and JOHANNns HIMARK, wholesale merchant, citizens of the Kingdom of Denmark, residing at Nrregade, Rdby, Denmark, and Vesterbrogade, 39, Copenhagen, Denmark, respectively, have invented certain new and useful Improvements in Benzene-Heated Stoves, of which the following is a specification. l

The prevent invention relates to lmprovements in stoves, employing benzene or the like for fuel.

An important object of the invention is to provide means to properly vaporize the benzene, and mix the same with air, such mixture being supplied to the burner.

A further object of the invention is to provide means to cut oil the supply of air to the benzene holding receptacle, when the apparatus is not in use.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the acompanying drawings, forming a part of this specification, and in which like reference characters are employed to designate like parts throughout the same,

Figure l is a central vertical sectional view through a stove embodying our invention, parts being shown in elevation, and

Fig. 2 is an enlarged central vertical sectional view through the burner.

The stove comprises a stationary lower casing a, and an upper casing Z), which is normally vertical. The casing ZJ is hinged to the casing a, at c. A latch Z normally serves to retain the casing ZJ in the vertical closed position.

The upper casing Z) has two horizontal plates e and f which hold in place a tubular combustion chamber g, and prevent the circulation of air between the same.

Arranged within the lower casing a, is a fuel receptacle L, having a vertical pivoted tube i rotatably mounted therein. This tube z' has its upper end rotatably fitting within a burner tube j, receiving the lower end of a burner le, provided at its top with an arch of wire gauze Z, as shown. Arranged vertically within the fuel holding receptacle 7L is an outer tube m, having a larger diameter than the tube z', and provided at its lower end with a reduced portion in which the lower end of the tube z' rotatably tits. The reduced Aportion of the tube m has an aperture m adapted to register with an aperture Z in the tube z'.

Surrounding the upper portion of the tube i is a ring o, to turn therewith. The ring o has an aperture o', adapted for movement into and out of registration with an opening L, in the tube m.

The outer tube m is provided at its top with a flange ma, engaging a top p, having apertures p. The top p has a horizontal slot p, receiving a horizontally swinging handle g, rigidly secured to the tube z' to turn it.

The tube d is provided in its lower portion with an aperture r, and the receptacle It is preferably filled with absorbent material n for the benzene, in the form of balls of Agaricas aZZius and PoZyporas aZbus, powdered and kneaded together with an adhesive.

A distributer s of wire gauze is disposed at the lower end of the combustion chamber g, and surounds the burner tube The burner lc is lighted throuffh openings covered by doors 'u and 15, whici doors are connected by a rod o, to move together, as shown.

In operation, the benzene is supplied to the absorbent balls within the receptacle l1.. The tube e' is then turned to bring aperture o into registration with aperture h and aperture m into registration with aperture Z. Air is thereby supplied into the upper end of the receptacle ZL, as indicated by the arrow, and the vaporized benzene which is mixed with the air passes through apertures Z and m', into the lower end of the tube z'. In this tube this mixture receives further air through the aperture r and the final mixture passes to the burner ic, and out through the gauze Z, to be ignited, in the presence of further air passing through the distributer s.

By turning the tube z' the apertures o and it', and Z and m are moved out of registration, and the supply of air cut oi from the receptacle 7L, and the supply of vaporized benzene cut oil from the tube z'.

Having thus described our invention what we claim is:

A stove of the character described comprising a vertical casing, a tubular combustion chamber extending axially within the casing and spaced therefrom so as to provide an annular chamber between the walls of the combustion chamber and casing, said combustion Chamber and easing walls having alining openings, horizontal plate fitted in the lower portion of the annular chamber and encircling the lower end ofthe combustion chamber so as to prevent the entrance of air into and its pasSage through said annular chamber, a tubular burner projecting into the lower end of the combustion chamber and adapted to be lighted through said registering openings, a pair of doors associated with Said openings for closing the same and Connected together to move in uur son, a Wire gauze distributer arranged at the lower end of the combustion `chamber vand surrounding the tubular burner to permit the passage of air into said combustion chamber, and means for supplying fuel to the burner.

In testimony whereof We aix our signatures.
